WebMay 31, 2024 · The performance of the active headrest was investigated through real-time experimentation involving sensors, actuators, and electronic devices. The test results showed that up to approximatively 20 dB of sound attenuation could be realized in the passenger’s ears over a narrowband sound field replicated under laboratory conditions.

WebThe performance of an active headrest was studied for head movement. It was previously known that when the head is moved, the secondary path in ANC is changed and hence the ANC performance is degraded. However, through experimental evaluation, it is established in this paper that the secondary path change has hardly any effect on ANC ... WebIn an active noise-reducing headrest with virtual microphones, the noise attenuation achieved at the ears of the listener usually decreases significantly as the head moves away from the central seat position. This paper presents a study on designing an active headrest with robust performance against head movement. To solve this problem, a minimax …
